Didn't mean to sound like a shitty response but this obsession with transfer fees gets on my man tits.
Sanchez was a free transfer and will cost United upwards of 200m but was a net spend of 0 according to Sky etc.
But, If we sell John Stones for 25m and buy KK for 63 this will be seen as net minus 38m.
The reality is JS has run down 3/5 of his transfer fee (so we still owe 20m of the original 50m).
Stones is off books at 10m year amortised transfer fee. KK on books for a little over 12m a year. Even if fee was 70m it would be around 14m a year. Assuming wages are similar then annual net spend is between plus2m and 4m on books. Marginal as I said...
